Thanks, pushed, closing.

%s is for use to include the contents of a string.  In the current case
we're including a symbol.  For symbols %s and %S behave identically,
tho, so it doesn't matter very much.  I do think %S is the better option
(e.g. it will make it clear if/when the arg is a string rather than
a symbol, for example, since it will put "..." around the contents), but
it's not important enough to go and change the `easy-mmode.el` code.
